CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Patent Application No. PCT/EP2005/007821 filed on Jul. 19, 2005 which is incorporated herein by reference in its' entirety which also claims the benefit of priority of German Patent Application No. 10 2004 037 554.2 filed on Aug. 3, 2004.

FIELD OF THE INVENTION

The present invention relates generally to compounds for the treatment of metabolic disorders such as type-2 diabetes, hyperglycemia, arteriosclerotic diseases and the like. Specifically, the present invention relates to compounds that inhibit the activity of dipeptidyl peptidase IV (DPP-IV) and are thus very suitable for lowering the blood glucose level. More specifically, the present invention relates to substituted 8-aminoalkylthioxanthines, their physiologically tolerated salts and functional derivatives and their therapeutic use as blood sugar-lowering agents among others.

BACKGROUND OF THE INVENTION

The enzyme dipeptidyl peptidase-IV (DPP-IV) inactivates a variety of bioactive peptides, including glucagon-like peptide-1 (GLP-1) and growth hormone releasing hormone (GHRH). Inhibiting DPP-IV in order to increase circulating GLP-1 is of interest as a treatment for Type II diabetes. Inactivation of DPP-IV may also increase circulating GHRH, potentially enhancing growth in domestic animals 8-(2-Aminoethylsulfanyl)-1,3,7-trimethyl-3,7-dihydropurine-2,6-dione has been described in the literature. This compound acts on the central nervous system (J. Med. Chem. (1966), 9 500-6). Inhibition of DPP-IV increases the circulating half-life of the incretin hormones GLP-1 and GIP, improving glucose tolerance in Type II diabetics. Complete inhibition of DPP-IV does not appear to be necessary: 2- to 3-fold increases in plasma concentrations of GLP-1 have been achieved in mice with inactivation of 84% to 96% of plasma DPP-IV Thus, there has been much interest in developing DPP-IV inhibitors for the treatment of Type II diabetes

DPP-IV exists as both a membrane-spanning form present in cells throughout the body and a soluble circulating form. Both forms of DPP-IV have identical enzymatic activity and cleave a wide range of bioactive peptides in vitro, including hormones, neuropeptides, and chemokines. One potential regulatory role of DPP-IV is the inactivation of GHRH through cleavage of the active form, GHRH(1-44)-NH₂, to the N-terminally shortened inactive form, GHRH(3-44)-NH₂, While trypsin-like degradation of GHRH also occurs, in vitro studies using GHRH analogs designed to resist cleavage at the N-terminus have demonstrated that the primary degradation of GHRH is via DPP-IV. Substitution of Ala2 with Dali prevents DPP-IV proteolysis and administration of this analog increases GH release in swine up to 2-fold. The His1, Val2 analog of GHRH is also not degraded by DPP-IV in vitro, and it demonstrates increased plasma stability over native GHRH. GHRH analogs containing the His1, Val2 substitutions were 5.4- to 12.5-fold more potent than native GHRH in release of GH in swine. Thus, inhibition of DPP-IV in vivo may increase endogenous concentrations of GHRH and enhance GH secretion.

The present ©invention is based on the object of providing compounds which display a therapeutically utilizable blood glucose-lowering effect. -(2-Aminoethylsulfanyl)-1,3,7-trimethyl-3,7-dihydropurine-2,6-dione has been described in the literature. This compound is also known to act on the central nervous system (J. Med. Chem. (1966), 9 500-6).

The compound(s) of the formula (I) may also optionally be administered in combination with one or more additional active ingredients.

The amount of a compound of formula I necessary to achieve the desired biological effect depends on a number of factors, for example the specific compound chosen, the intended use, the mode of administration and the clinical condition of the patient. The daily dose is generally in the range from 0.3 mg to 100 mg (typically from 3 mg and 50 mg) per day and per kilogram of bodyweight, for example 3-10 mg/kg/day. An intravenous dose may be, for example, in the range from 0.3 mg to 1.0 mg/kg, which can suitably be administered as infusion of 10 ng to 100 ng per kilogram and per minute. Suitable infusion solutions for these purposes may contain, for example, from 0.1 ng to 10 mg, typically from 1 ng to 10 mg, per milliliter. Single doses may contain, for example, from 1 mg to 10 g of the active ingredient. Thus, ampoules for injections may contain, for example, from 1 mg to 100 mg, and single-dose formulations which can be administered orally, such as, for example, capsules or tablets, may contain, for example, from 1.0 to 1000 mg, typically from 10 to 600 mg. For the therapy of the abovementioned conditions, the compounds of formula I may be used as the compound itself, but they are preferably in the form of a pharmaceutical composition with an acceptable carrier. The carrier must, of course, be acceptable in the sense that it is compatible with the other ingredients of the composition and is not harmful for the patient's health. The carrier may be a solid or a liquid or both and is preferably formulated with the compound as a single dose, for example as a tablet, which may contain from 0.05% to 95% by weight of the active ingredient. Other pharmaceutically active substances may likewise be present, including other compounds of formula 1. The pharmaceutical compositions of the invention can be produced by one of the known pharmaceutical methods, which essentially consist of mixing the ingredients with pharmacologically acceptable carriers and/or excipients.

Pharmaceutical compositions of the invention are those suitable for oral, rectal, topical, peroral (for example sublingual) and parenteral (for example subcutaneous, intramuscular, intradermal or intravenous) administration, although the most suitable mode of administration depends in each individual case on the nature and severity of the condition to be treated and on the nature of the compound of formula I used in each case. Coated formulations and coated slow-release formulations also belong within the framework of the invention. Preference is given to acid- and gastric juice-resistant formulations. Suitable coatings resistant to gastric juice comprise cellulose acetate phthalate, polyvinyl acetate phthalate, hydroxypropylmethylcellulose phthalate and anionic polymers of methacrylic acid and methyl methacrylate.

Suitable pharmaceutical compounds for oral administration may be in the form of separate units such as, for example, capsules, cachets, lozenges, chewable tablets, each of which contain a defined amount of the compound of formula l; as powders or granules, as solution or suspension in an aqueous or nonaqueous liquid; or as an oil-in-water or water-in-oil emulsion. These compositions may, as already mentioned, be prepared by any suitable pharmaceutical method which includes a step in which the active ingredient and the carrier (which may consist of one or more additional ingredients) are brought into contact. The compositions are generally produced by uniform and homogeneous mixing of the active ingredient with a liquid and/or finely divided solid carrier, after which the product is shaped if necessary. Thus, for example, a tablet can be produced by compressing or molding a powder or granules of the compound, where appropriate with one or more additional ingredients. Compressed tablets can be produced by tableting the compound in free-flowing form such as, for example, a powder or granules, where appropriate mixed with a binder, glidant, inert diluent and/or one or more surface-active/dispersing agent(s) in a suitable machine. Molded tablets can be produced by molding the compound, which is in powder form and is moistened with an inert liquid diluent, in a suitable machine.

Pharmaceutical compositions which are suitable for peroral (sublingual) administration comprise lozenges and chewable tablets which contain a compound of formula I with a flavoring, normally sucrose and gum arabic or tragacanth, and pastilles which comprise the compound in an inert base such as gelatin and glycerol or sucrose and gum arabic.

Pharmaceutical compositions suitable for parenteral administration comprise preferably sterile aqueous preparations of a compound of formula I, which are preferably isotonic with the blood of the intended recipient. These preparations are preferably administered intravenously, although administration may also take place by subcutaneous, intramuscular or intradermal injection. These preparations can preferably be produced by mixing the compound with water and making the resulting solution sterile and isotonic with blood. Injectable compositions of the invention generally contain from 0.1 to 5% by weight of the active compound.

Pharmaceutical compositions suitable for rectal administration are preferably in the form of single-dose suppositories. These can be produced by mixing a compound of the formula I with one or more conventional solid carriers, for example cocoa butter, and shaping the resulting mixture.

Pharmaceutical compositions suitable for topical use on the skin are preferably in the form of ointment, cream, lotion, paste, spray, aerosol or oil. Carriers which can be used are petrolatum, lanolin, polyethylene glycols, alcohols and combinations of two or more of these substances. The active ingredient is generally present in a concentration of from 0.1 to 15% by weight of the composition, for example from 0.5 to 2%.

Transdermal administration is also possible. Pharmaceutical compositions suitable for transdermal uses can be in the form of single patches which are suitable for long-term close contact with the patient's epidermis. Such patches suitably contain the active ingredient in an aqueous solution which is buffered where appropriate, dissolved and/or dispersed in an adhesive or dispersed in a polymer. A suitable active ingredient concentration is about 1% to 35%, preferably about 3% to 15%. A particular possibility is for the active ingredient to be released by electrotransport or iontophoresis as described, for example, in Pharmaceutical Research, 2(6): 318 (1986).

Further active ingredients suitable for combination products are: all antidiabetics mentioned in the Rote Liste 2004, chapter 12. They may be combined with the compounds of the formula I of the invention in particular for a synergistic improvement of the effect. Administration of the active ingredient combination may take place either by separate administration of the active ingredients to the patient or in the form of combination products in which a plurality of active ingredients are present in one pharmaceutical preparation. Most of the active ingredients listed below are disclosed in the USP Dictionary of USAN and International Drug Names, US Pharmacopeia, Rockville 2001.

Caromax® is a carob-containing product from Nutrinova, Nutrition Specialties & Food Ingredients GmbH, Industriepark Höchst, 65926 Frankfurt/Main)). Combination with Caromax® is possible in one preparation or by separate administration of compounds of the formula I and Caromax®. Caromax® can in this connection also be administered in the form of food products such as, for example, in bakery products or muesli bars.

The compounds of the formula I are notable for beneficial effects on lipid and carbohydrate metabolism, in particular they lower the blood glucose level and are suitable for the treatment of type 2 diabetes, of insulin resistance, of dyslipidemias and of metabolic syndrome/syndrome X. The compounds are also suitable for the prophylaxis and treatment of arteriosclerotic manifestations. The compounds can be employed alone or in combination with other blood glucose-lowering active ingredients. The compounds act as DPP-IV (dipeptidyl peptidase IV) inhibitors and are also suitable for the treatment of disorders of wellbeing and other psychiatric indications such as, for example, depressions, anxiety states, anxiety neuroses, schizophrenia and for the treatment of disorders associated with the circadian rhythm, for weight reduction in mammals, for the treatment of immunological disorders, and for the treatment of drug abuse.

They are also suitable for the treatment of cancer, arthritis, osteoarthritis, osteoporosis, sleep disorders, sleep apnea, female and male sexual disorders, inflammations, acne, pigmentation of the skin, disorders of steroid metabolism, skin diseases, psoriasis, mycoses, neurodegenerative diseases, multiple sclerosis and Alzheimer's disease.

It will be appreciated that every suitable combination of the compounds of the invention with one or more of the aforementioned compounds and optionally one or more other pharmacologically active substances is regarded as falling within the protection conferred by the present invention.

The compounds of the formula I can be prepared by reacting suitable starting materials of the formula II, in which R1, R2 and R3 have the meaning indicated above, and X is a leaving group such as chlorine, bromine, iodine, sulfonyloxide, sulfinyl, sulfoxyl, with a compound of the formula V, where appropriate in the presence of suitable bases, to give the compounds of the formula IV where X is a suitable leaving group such as, for example, chlorine, bromine, iodine, sulfonyloxi, sulfinyl or sulfoxyl. Alternatively, compounds of the formula III in which R1, R2 and R3 have the meaning indicated above are reacted with alkylating agent of the formula VI to give the compounds of the formula IV, where X is a suitable leaving group such as, for example, chlorine, bromine, iodine, sulfonyloxi, sulfinyl or sulfoxyl.

In the cases where R4 or R5 is hydrogen, it may be expedient to employ the radical —NR4R5 in a form protected on the nitrogen function, and to eliminate the protective group again at a suitable point in the reaction. Such suitable protective groups and the methods for introducing and eliminating are known (see:Theodora W. Greene and Peter G. M. Wuts, Protective Groups in Organic Synthesis, 3rd edition, John Wiley & Sons, Inc., New York, 1999 )

The thioether function in IV can then be oxidized by known methods to give the substances of the invention of the formula I in which n is a number 1 or 2.

The halogen compounds of the formula II can be obtained by known methods such as, for example, by halogenation of the corresponding H or OH compound (formula 2, X═H, OH). Suitable halogenating agents may be for example halogens such as chlorine and bromine, N-bromo-succinimide, phosphorus pentoxide or phosphorus oxichloride.

The compounds of the formula III can be obtained by reacting the halogen compounds of the formula II with suitable reagents such as, for example, hydrogen sulfide or thiourea by known methods.

The synthesis of compounds of the formula II and III is described many times in the literature (see Houben Weyl E9b/2, pp. 331 et seq.). They can be obtained for example starting from diaminopyrimidine derivatives or aminoimidazolecarboxamides by reaction with suitable reagents, and be converted by targeted chemical modifications such as hydrolysis, alkylation, halogenation into the desired starting compounds of the formula II or III.

The radicals R1 to R3 can be prepared by methods known per se by alkylating appropriate precursors, it being possible to vary the sequence. However, in some cases, they can also be introduced by the selection of appropriate precursors in the preparation of the xanthine structure.

The examples detailed below are provided to better describe and more specifically set forth the compounds, processes and methods of the present invention. It is to be recognized that they are for illustrative purposes only however, and should not be interpreted as limiting the spirit and scope of the invention as later recited by the claims that follow.

The activity of the compounds was assayed as follows:

a) Measurement of the DPP-IV Activity:

Material:

DPP-IV from porcine kidney (Sigma Chemical Co, Munich DE)

H-Ala-Pro-AFC (Bachem Chemical Co, Weil am Rhein DE)

Assay Conditions:

Dipeptidyl peptidase-IV (DPP-IV) (1 mU/ml, final concentration)

H-Ala-Pro-AFC (15 μM, final concentration)

in Tris/HCl (40 mM, pH 7.4), total volume 0.2 ml

The reaction was carried out at room temperature for various times (typically 10 min) and stopped at the end of the reaction by adding 20 μl of ZnCl₂(1M). The H-Ala-Pro-AFC conversion was determined fluorimetrically by measuring the emission at 535 nm after excitation at 405 nm. When inhibitors were added, the added buffer volume was adapted so that a total volume of 200 μl was maintained for the assay mixture.

IC₅₀ values for inhibitors were determined by varying the inhibitor concentrations with the stated substrate concentration of 15 μM. Ki and Km values were found by appropriate variation of substrate concentration and inhibitor concentration as described (Dixon, M. and Webb, E. C.(1979) Enzymes, third edition, pp. 47-206, Academic Press). The values for Km, IC₅₀ and Ki were calculated using a commercially available software package (Leatherbarrow, R. J. (1992) GraFit Version 3.0, Erithacus Software Ltd. Staines, U.K.).
